Diagnostic Test

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

AAT SENSOR VOLTAGE BELOW 0.3 OF A VOLT
1. Ignition on, engine not running.
2. With a scan tool, read the AAT voltage.
  Is the voltage below 0.3 of a volt?
  
  Yes
  - Go to step 2
  No
  - Perform the INTERMITTENT CONDITION Diagnostic Procedure. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
AAT SENSOR
1. Turn the ignition off.
2. Disconnect the AAT harness connector.
3. Ignition on, engine not running.
4. With a scan tool, read AAT voltage.
  Is the voltage above 1.0 volt?
  
  Yes
  - Replace the AAT Sensor.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 3
(G31) AAT SIGNAL CIRCUIT SHORTED TO THE (G931) SENSOR GROUND CIRCUIT
1. Turn the ignition off.
2. Disconnect the C2 TIPM harness connectors.
3. Measure the resistance between the (G931) Sensor Ground circuit and the (G31) AAT Signal circuit in the AAT Sensor harness connector.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the short to between the (G931) Sensor Ground circuit and the (G31) AAT Signal circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 4
(G31) AAT SIGNAL CIRCUIT SHORTED GROUND
1. Measure the resistance between ground and the (G31) AAT Signal circuit in the AAT Sensor harness connector.
  Is the resistance below 100 Ohms?
  
  Yes
  - Repair the short to ground in the (G31) AAT Signal circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Go to step 5
TOTALLY INTEGRATED POWER MODULE (TIPM)
NOTE: Before continuing, check the TIPM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
1. Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
  No
  - Replace and program the Totally Integrated Power Module in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
